Probably not. The Linux driver downloads its own microcode into the
HA, so you are probably OK. I have a 2940U (dang near the same thing)
and have never upgraded its bios.
First, is the kernel detecting the thing properly. Run "less
/proc/pci" and you should see something like:
Bus 0, device 13, function 0:
SCSI storage controller: Adaptec AIC-7861 (rev 1).
IRQ 11.
Master Capable. Latency=32. Min Gnt=4.Max Lat=4.
I/O at 0xd800 [0xd8ff].
Non-prefetchable 32 bit memory at 0xed800000 [0xed800fff].
The computer's BIOS is finding it, or you wouldn't have the SCSI BIOS
'not installed' message. This means the firmware on the HA didn't find
your hard drive, which suggests a termination or addressing issue.
To check this, reboot and go into the firmware on the HA as you
boot. Unless a previous user has turned off the option, you should get
a message from the BIOS at boot time indicating which key to press to
get in. I think it's F1, but I'm not sure.
In the firmware, you should see a menu to test hard drives. Try
that. NB: The test is DESTRUCTIVE, so do NOT actually perform it! But
you should get a menu of all the hard drives the HA finds. If you
don't see all your hard drives, I would suspect either a termination
problem or a SCSI addressing problem.
I recommend you turn off auto termination and do it manually. It's
very simple. The HA's manual should tell you how to do it.
